What September is like in Puerto Rico

September is the heart of hurricane season, with highs near 89F (32C) and heavy humidity. It was the month of both Maria in 2017 and Fiona in 2022. Some smaller hotels, restaurants and tour operators close for a few weeks, especially on Vieques and Culebra. Prices and crowds are at their lowest.

Avoid it unless you are flexible and insured. If you do go, stay in San Juan, where services are most reliable. Keep an eye on the tropics daily. For the best weather and full services, choose December through April.

Things to do in Puerto Rico

Full guide

Castillo San Felipe del Morro and Castillo San Cristobal

The two great forts of San Juan National Historic Site. Go at opening before the cruise-ship wave, then fly a kite on El Morro's lawn like the locals do.

Official site ↗Tickets and tours →

El Yunque National Forest

Waterfalls, cloud forest, and the tower views from Yokahu and Mt. Britton. Check the forest's site for current access rules and reservations before you go, and start early to beat both crowds and afternoon rain.

Official site ↗Tickets and tours →

Mosquito Bay, Vieques

Paddle a kayak through glowing water on a moonless night. Swimming is prohibited to protect the organisms; schedule around the new moon for the best show.

Tickets and tours →

Flamenco Beach, Culebra

A horseshoe of white sand regularly ranked among the best beaches in the Caribbean. Ferries from Ceiba fill fast on weekends and holidays; small planes are the backup.

Tickets and tours →

Old San Juan on foot

Calle del Cristo, the Paseo de la Princesa, and the city walls at sunset. Weekday evenings after the cruise ships leave are the calmest.

Tickets and tours →

Rincon and the west coast

The island's surf capital, busy with swells roughly November through March and glassy for snorkeling in summer. Sunsets here face the open sea.

Beat the crowds

Check the cruise schedule for San Juan: Old San Juan is noticeably busier on multi-ship days, so do the forts and Calle del Cristo on light days or after 4pm.
Aim for the post-Easter window in late April and early May, when winter weather mostly holds and hotel rates fall.
Do El Yunque at opening on a weekday. By late morning the main trail parking fills, and afternoon showers are common.
Book Vieques and Culebra ferries or flights well ahead for weekends and holidays, when locals fill the boats too; midweek is far easier.

Know before you go

September and October: some smaller hotels, restaurants, and tour operators close for a few weeks of maintenance or vacation, especially on Vieques and Culebra. Verify before building a trip around one.
The bioluminescent bays are best on moonless nights and can dim temporarily after heavy rain or storms. Tour operators will tell you honestly how the bay is glowing that week.
El Yunque's roads and trails can close after heavy rain or storm damage; check current conditions and any reservation requirement on the official forest site before driving out.
Major holidays (Christmas Eve, Christmas Day, New Year's Day, Three Kings Day, Good Friday) shut government offices and many shops; restaurants in tourist areas mostly stay open.
